In original GNU libgcc, _Unwind_Backtrace is published with GCC_3.3 version for all architectures but ARM. For ARM should be publishes with GCC_4.3.0 version. This was originally omitted in r255095, fixed in r318024 and omitted aging in LLVM libunwind implementation in r354347. For ARM _Unwind_Backtrace should be published as default with GCC_4.3.0 version , (because this is right original version) and again as normal(not-default) with GCC_3.3 version (to maintain ABI compatibility compiled/linked with wrong pre r318024 libgcc) PR: 233664 (cherry picked from commit e8141ad1df2098dd3f6d627c49ce99307315f5fd) contrib/llvm-project/libunwind/src/UnwindLevel1-gcc-ext.c | 4 ++++ 1 file changed, 4 insertions(+) -- You are receiving this mail because: You are on the CC list for the bug.
